Your Claude is coding blind. See everything it did.
demo.mp4
Claude Code started hiding what it does.
Since v2.1.20, Claude Code replaced detailed output with opaque summaries. Read 3 files. Searched for 1 pattern. Edited 2 files. No file paths. No content. No line numbers. The community backlash was immediate.
But the problem goes deeper than collapsed file paths:
- Thinking steps — Claude's chain-of-thought reasoning is completely invisible in the terminal
- Tool call details — you see a one-line summary, not the actual input/output
- Subagent activity — agents spawn agents, but you only see the final result
- Context window — a three-segment progress bar with no breakdown of what's consuming your tokens
- Team coordination — teammate messages, task delegation, shutdown requests — all buried
The only workaround is --verbose, which dumps raw JSON, internal system prompts, and thousands of lines of noise. There is no middle ground.
claude-devtools reads ~/.claude/ — the session logs already on your machine — and reconstructs everything.
| What the terminal hides | What claude-devtools shows |
|---|---|
Read 3 files |
Exact file paths, syntax-highlighted content with line numbers |
Searched for 1 pattern |
The regex pattern, every matching file, matched lines |
Edited 2 files |
Inline diffs with added/removed highlighting |
| Three-segment context bar | Per-turn token attribution across 7 categories with compaction visualization |
| Collapsed subagent output | Full execution trees per agent with tool traces, tokens, duration, cost |
| Nothing about thinking | Extended thinking content, fully visible |
--verbose JSON dump |
Structured, filterable, navigable interface — no noise |
Zero configuration. No API keys. No wrappers. Works with every session you've ever run.

Per-turn token attribution across 7 categories — CLAUDE.md (global, project, directory), skills, @-mentioned files, tool I/O, thinking, team overhead, user text. See exactly what's in the context window at any point.
compact.mp4
See the moment your context hits the limit. Visualizes how context fills, compresses, and refills — so you know exactly what was lost.
noti.mp4
System notifications for .env access, tool errors, high token usage, and custom regex patterns on any field.
Every tool call expanded with specialized viewers — syntax-highlighted Read calls, inline Edit diffs, Bash output, and full subagent trees.
Isolated execution trees per agent with tool traces, token metrics, duration, and cost. Nested agents render recursively.
Inspect sessions on any remote machine over SSH. Reads ~/.ssh/config, supports agent forwarding and key auth.
Cmd+K for cross-session search. Open multiple sessions side-by-side with drag-and-drop tabs.
claude-devtools does not wrap, modify, or interfere with Claude Code. It reads session logs that already exist on your machine. Works with sessions from the terminal, IDEs, or any tool that uses Claude Code.
Run without Electron — in Docker, on a remote server, or anywhere Node.js runs.
docker compose up
# Open http://localhost:3456Or manually:
docker build -t claude-devtools .
docker run -p 3456:3456 -v ~/.claude:/data/.claude:ro claude-devtools| Variable | Default | Description |
|---|---|---|
CLAUDE_ROOT |
~/.claude |
Path to the .claude data directory |
HOST |
0.0.0.0 |
Bind address |
PORT |
3456 |
Listen port |
The standalone server has zero outbound network calls. For maximum isolation: docker run --network none -p 3456:3456 -v ~/.claude:/data/.claude:ro claude-devtools. See SECURITY.md.
